Research Statement: 

Our lab focuses on understanding the signaling processes that underlie the decision to proliferate. Although many proteins regulating proliferation have been identified, it is still unclear how these central components are wired into circuits to carry out the decision of proliferation. In particular analysis of signaling dynamics in space and time and tools to probe interactions between components have been missing. To address these questions, we apply an automated imaging system and live-cell biosensors to monitor signaling processes at the single-cell level. We classify heterogeneous population and further explore underlying molecular mechanism. We are currently studying the decision of proliferation in normal condition and pathological condition, cancer.
